Claims.

This invention relates' to a terminal receptacle forlighting and electrical fixtures on gas ranges and the like and particularly to a new and improved mounting for an oven light such as de- 5 scribed in United States Letters Patent; No.

1,992,209,issued February 26, 1935.

As therein more fully described,it is necessary in oven light structures of this character, that the bulb shank and electric socket be exposed l0' to the outside air in a manner such that there is free circulation of air thereabout to cool the bulb and socket and preventheating of the bulb shank and socketto a dangerous degree. In order to obtain adequate ventilation and cooling, it is necessary tomount the socket entirely outside of the oven compartment with the bulb so arranged with'respect to the socket and oven compart ment as to light the interior of the oven through an aperture in its rear Wall.

Underwriting and electrical laboratories, howeveryrequire that electrical connections to-all such fixtures mustbe'fullyenclosed and protected so that the operator will not be in danger ofelectricalshock by contact therewith or short circuited currents therefrom.

In additiontotheoven-light'above described,

it hasbecome customary practice to provide illu-- minating lights -=for the tops :of the ranges and also'electrical electrical clocks, and other electrical fixtures.

One of 'the principal objects of the present invention-is to provide-a combined terminal receptacle and mounting for supporting and supplying current to an oven light in such manner that theielectrical: connections are entirely enclosed and: protected and-are maintained in relatively cool condition by circulation of air thereabout.

Axcorrelativeobject'is-to provide a terminal receptacle for this purpose in which suitable plug 40 sockets are provided for connectionto other electrical apparatus-utilized in connection with the range.

Still'anotherobject is to provide a terminal receptacle-which is mounted so that the fixtures thereof'may berendered'accessible readily to the operator to permit the bulb to be changed in the usual manner without danger'of short circuiting against the metal of the range or in any other manner during the installation or removal thereof.

Other objects and advantages will become apparent from the following specification wherein reference ismade to the drawings, in which:

* Fig. 1 is an end elevation of the range with a.

terminal receptacle embodying the' principles of-': the present inventionattached thereto;

Fig. 2 is a fragmentary rear elevation of them range 'and terminal receptacle illustr'ated'in Fig. 1;

Fig. 3 is an enlarged fragmentary rear eleva tion of a portion of the 'range showing the terminal receptacle and cooperating parts connected thereto, part of the receptaclebeing 'shown in 1 section; 10351 Fig.4 is a vertical sectionalview takenona plane indicated by the line 4-4 in Fig.3; and- Figs. 5 and 6 are horizontal sectional views taken on planes indicated by the lines 5--5 and- 6-6, respectively, in Fig. 4. 15

Referring to the drawings; the present invention is shown as installed ona range Lha-vingx anoven compartment 2 which is closed-at the front by a suitable downwardly swinging door 3.-

The range also carries a suitablesplash panel or 20a rear wall of the range so that the coverall I may 30.-

be lifted to an upright position and dropped behind the range. A suitable opening ll isprovided in the rear panel of the range to accommodatepassage of the coverall l. In addition, 3

the top wall or panel I2 of the range is secured 51.,

at its rear edge to the range by a suitable hinge !3 so that the entire top panel l2 may be lifted to a vertical position to permit access to the service burners for cleaning and repairs.

In the range in connection with which the 401::

present invention is illustrated, the oven has a rear wall IS in which is a suitable aperture I6, a metal liner or sleeve I! being provided to line the aperture. The liner I! is' provided atits inner end with a slightly inturned peripheral flange l8 which defines an annular abutment which is preferably slightly less in diameter than the bulb to be associated with the aperture so that the bulb may be seated from' the outside against the flange 18 and thus protrude slightly into the interior of the oven but without danger of passing entirelythereinto. Mounted on the rear wall of the oven is one arm 2!! of a suitable hinge, the otherarm 2| of which extends normally a predetermined distance from the rear of the range. Mounted on the arm 2| in spaced relation to the rear wall of the range is a terminal receptacle 22. As illustrated, the receptacle 22 preferably is comprised of imperforate sheet metal and is provided intermediate its ends with a sub-compartment 23 in which are carried the usual sockets 24 for receiving saber connections. Below the compartment 23 in the box 22 is a push button switch 25 which is rigidly mounted in the box and has the usual push button 26 extending outwardly therefrom towards the rear wall of the oven.

Mounted within the receptacle at the upper or opposite end thereof is a light socket 28, the light socket being fixedly secured to the front wall of the receptacle 22 and extending forwardly thereof so as to be accessible from the front thereof. Carried in the socket 28 is a bulb 29 which, when the receptacle is in an upright position, seats against the flange l8 of the liner H. The receptacle 22 is held in upright position by a suitable tension spring 39 connected at its ends to the rear wall of the even, as illustrated, and looped around the receptacle. The force of the spring 30 is resisted entirely by the bulb 29 engaging the flange l8. Suitable lead-in wires 33 extend through an opening in the bottom wall of the receptacle 22, and are protected within the receptacle opening by a suitable cushion 34 so as to eliminate any danger of abrasion of the lead-in wires by the edges of the opening. In order to protect the socket and other connections within the box from any pull occasioned by pulling the wires 33, the lead-in wires are knotted, as at 35, in the box,

thus providing a suitable anchor. The sockets 24 are connected in parallel to the lead-in Wires 33. The switch 25, on the other hand, is connected in series with the socket 28 and with the lead-in wires 33. The switch is so positioned that the button 26 is movable horizontally fore and aft of therange just above the floor of the oven.

An operating rod 38, carried by the range, extends from the button 2'6 to the front of the range in position to be engaged by the door 3. The switch is arranged to complete the circuit to the light when the door is in open position and to break the circuit through the medium of the rod 38 when the door is moved to closed position. For this purpose the outer end of the rod adjacent the front of the range is positioned in such manner as to be engaged by the door 3 itself upon lift ing thereof to closed position.

Carried on the arm 2! is a suitable stop 39 which, when the receptacle 22 is swung outwardly from the rear oven wall, as indicated in the dotted lines in Fig. 4, engages the rear wall of the oven and stops the receptacle substantially in this position so that it is easily accessible to the operator.

Suitable lead wires 40 and ll lead to the light 5 and clock 8 respectively, these wires being provided with the usual saber plug-in connections for engagement with the sockets 24 respectively. It will be seen that the socket 28 and the shank of the bulb 29 are positioned entirely in the open behind the oven wall and out of contact therewith so as to be ventilated freely and thus prevented from reaching a temperature which might be dangerous to the bulb or socket. Furthermore there is no metal to metal conduction'of heat from the range into the socket and bulb shank. The same is true as to the plug-in sockets 24 and switch 25. In addition, all incidental electrical connections are entirely protected both from the heat of the oven and from exposure to the operator and all parts are so arranged that there is no dangerous flexure of any wire or connection during opening and closing of the receptacle 22.
